The online retailer and reviews site currently lists more than 160 string trimmer models and publishes nearly 500 reviews from actual customers and shoppers.

The new algorithm generates a specific letter grade for every individual string trimmer, allowing StringTrimmersDirect.com to now publish the most comprehensive 2014 string trimmer lists online.

“Some best-selling lists online are randomly generated by affiliate sites looking for a commission,” said Joe Delulio, turf expert at StringTrimmersDirect.com. “Other top-rated lists by magazines are so old that most models are already discontinued.”

According to Delulio, the String Trimmers Direct lists are the best source for 2014 string trimmer rankings for three distinct reasons:

1. Three Lists in One
The word “best” means different things to different people. StringTrimmersDirect.com publishes lists that can be sorted three ways. Shoppers can sort string trimmers by best selling, top-rated or expert recommended models. In addition, the results can be filtered, narrowing the selection of trimmers significantly.

One list wasn’t good enough for StringTrimmersDirect.com. The online retailer created separate lists for each of the four styles of string trimmers, ranging from small electric trimmers to large walk-behind wheeled trimmers.

2. Real-Time
The majority of best-selling lists are updated once a year, showcasing discontinued trimmers that were popular last year. String Trimmers Direct's lists, however, are updated in real-time, highlighting what’s hot and what’s popular in 2014.

“Best of all, actual string trimmer users influence the algorithm daily. If you don’t agree with our letter grade, you simply submit a review, which instantly alters the ranking,” said Delulio, who personally works directly with all of the leading manufacturers and actual customers before recommending the highest quality trimmers.

3. Free
StringTrimmersDirect.com doesn’t require a sign-up form or a subscription. The retailer’s goal is to educate shoppers with free information, helping them pick the perfect string trimmer.

"We're so passionate about string trimmers that we're delighted to share this valuable information for free," said Delulio.
